Gorgeous girl, extremely passionate (9)
I believe the answer is:
glamorous
'gorgeous' is the definition.
(I've seen this before)
'girl extremely passionate' is the wordplay.
'extremely' says to hollow out the word (remove centre letters).
'passionate' becomes 'amorous' (similar in meaning).
'girl' with its middle taken out is 'gl'.
'gl'+'amorous'='GLAMOROUS'
(Other definitions for glamorous that I've seen before include "Smart; glittering" , "Alluring" , "in a showy way?" , "Sophisticated and stylish" , "Alluringly appealing" .)
